I am 34 years old, living in the south, married, 160 cm, 52 kg, 32D/25/34, working as an accountant in a private organization. My husband is 36 years old, working in a state-owned enterprise, and he is also a union cadre of the enterprise. My mother-in-law, 63 years old, is always at home. When she has nothing to do, she often invites a few friends to travel, so she is not at home for more than ten days every month. Our family of three lives in a three-story house. The first floor is a garage, and the living room, kitchen, bathroom, bedroom, etc. are on the second and third floors.

My husband has a good friend who he has known for many years. His name is Ming. He works as a physical education teacher in a high school. He is 172 cm tall, weighs about 70 kg, and has some muscles... He is not handsome, but he has a strong personality and is quite humorous in his conversation. I heard that he is the secret crush of many young girls in the school.

Ming and my husband have known each other since high school, and they live near my in-laws' home, so he is familiar with my in-laws and often visits them. In fact, my in-laws and I don't treat him as an outsider.

Today, my husband went to the north to attend a meeting on behalf of the union and will be back the next day. My mother-in-law went to the central mountain area with her best friend and will be back in two days. So, I am the only one at home today.

Since I have to wear a tight skirt, shirt and tights to work, it's okay in winter, but the weather in the south is hot in summer. Wearing tights, the skirt will feel wet and sticky all day long. As soon as I got home, I took a shower and changed into a spaghetti strap sleeveless camisole and short shorts.

I was preparing my own dinner when I heard someone ring the doorbell.

I went downstairs and opened the door. It was Ming. He had just come back from school. He was wearing shorts and a vest. His posture showed his strong chest muscles and round buttocks.

I took him to the living room on the second floor. As soon as we sat down, he asked me if my father-in-law had finished get off work. In fact, he should know that my father-in-law had not yet come home after get off work.

I replied to him: My husband will not be back today. He went to Taipei for a meeting and will be back tomorrow.

He said: That's a pity. I wanted to buy some silk briefs. They are quite comfortable for me. Doesn't your father-in-law also wear briefs? I want your father-in-law to pick out some.

I thought to myself: My husband’s briefs are really old. I wanted to buy him a few pairs, but I was so busy that I forgot about it.

Just when I was lost in thought, Ming called me.

I need to use the toilet urgently.

Before I could reply, he hurried to the bathroom. My house has a full bathroom on the second floor, and a separate toilet on the third floor, so when we have visitors, my father-in-law and I always take them to the toilet on the third floor.

I thought to myself, Ming must be really in a hurry, otherwise why wouldn’t he go to the bathroom on the third floor?

After a while, it came out clearly.

He sat down and I offered him a drink.

We sat down and Ming spoke:

My sister-in-law has a great figure, your father-in-law is so lucky!

I said: Xiaozhen has a good figure too! Very plump!

Xiao Zhen is Ming's wife, 158 cm, 55 kg, 34C, 26, 36, and works as a nurse in the hospital.

Ming said: Xiaozhen is a little fat and her breasts are a little saggy, but you, sister-in-law, have a good figure!

I was secretly proud of what I heard! Actually, I had seen Xiaozhen in a swimsuit before when I went to Baolai Hot Springs with my husband, Mingdong and Xiaozhen. How could I not know her figure?

Ming went on to say: You don’t know, I told her that you can’t just buy random underwear, it will deform your breasts!

I said: Ming, Xiaozhen is also saving money for you. Doesn't she want to buy such expensive underwear? You still blame her!

Ming said: I told her to buy better ones, so that she can wear them for a longer time and prevent her breasts from sagging. Sister-in-law, your breasts are very firm.

I said: Ming, don't be so frivolous, you are already a few years old. In fact, I am still very happy when I am praised by others.

Ming said: Sister-in-law, your underwear is very expensive, right? Your husband is so nice, he really lets you spend money.

I thought to myself, I have always worn CK. I like this brand of underwear, most of which are made of tulle and make the breasts look beautiful. Of course, the price is not cheap.

I said: Ming, you are wrong. My husband would never let me buy such expensive underwear. I bought them with my own salary.

Ming said: Oh! I have never heard of the CK you mentioned producing underwear.

I said: Yes! CK has released many products, including clothing and watches!

Ming said: Oh! The one I saw in the bathroom was CK's!

I thought, oh no! I just took a shower and my clothes are still in the laundry basket. He must have seen them when he went to the bathroom. And I was wearing CK thongs to work today. Now I feel like he's been spied on.

At this time, your heartbeat is a little fast, your breathing is a little rapid, and your face must be a little red!

I got a little angry and quickly stood up and said, "Ming, how could you peek at my underwear? You're going too far!"

My tone was a little anxious at this time, actually I was a little nervous and uneasy.

Mingji also stood up and explained: Sister-in-law, I didn't mean it. I just saw your underwear and thought of Xiaozhen's underwear. I felt that your style was very different from Xiaozhen's. I was curious at the moment, so I picked it up to take a closer look. Don't be angry!

At this moment, I found his reaction a little funny, so I sat back on the sofa and laughed unconsciously.

When Ming saw me smile, he sat down with relief and said: Sister-in-law, I thought you were angry, I was scared to death.

The moment Ming sat down, he saw the important part of Dong's underwear through the gap in his shorts.

A bit absent-minded.

Ming said: Sister-in-law, don’t blame me for being indecent. Your underwear is really beautiful and suits your figure very well. Xiaozhen may not look as good in it as you do.

I felt so excited after being praised by him.

Ming then said: Sister-in-law, when you were standing just now, I stole a glance at you and saw that your butt was very raised. Are you wearing a thong?

I said: "Yes! When wearing a thong, the buttocks will be more beautiful, and I can wear a tight skirt to work without showing the edge of my underwear. Ming, Xiaozhen wears a nurse uniform to work, so she should wear a thong, and her buttocks will be beautiful too!"

Ming said: Yes, her birthday is coming soon, I should buy her a nice set of underwear to surprise her. She is reluctant to buy it anyway, so I might as well buy it for her as a birthday present, she will definitely be very happy.

But, sister-in-law, I am a man and don’t understand this very well. Can you teach me?

After listening to this, I was a little confused and didn't know what to do next.

After a while, I said: How to teach?

Jianming hurried to the bathroom. Before I could stop him, he took out the underwear I had just changed, spread it out in front of me and said:

Now tell me, how to choose underwear suitable for Xiaozhen.

Before I could open my mouth, Ming spoke:

Sister-in-law, the underwear you changed out of still has a faint body fragrance! By the time I reacted, he had already picked up the underwear and put it to his nose to smell it, saying:

Wow! Sister-in-law, what a strong body odor!

After hearing this, I remembered that when I was taking a break at the company at noon today, I was watching TV in the company and accidentally turned to the porn channel. When I watched it, my pussy secreted a lot of vaginal fluid.

When I came to my senses, my breathing became more rapid and my heart beat faster, and the plot of the porn movie I saw in the company lounge at noon came to my mind.

Unconsciously, I felt the temperature in the room getting hotter. I saw a scene in front of me: a man other than my husband was sniffing my underwear and praising my figure. I felt a different feeling in my pussy. I also felt a little bit of vaginal fluid flowing out of it. It was like the feeling after my period, when I always longed for my husband's cock to penetrate my pussy, but I couldn't feel the fullness and emptiness in my pussy.

When I was eager to have sex, the muscular and toned man in front of me, his penis was erect with blood and veins, and the urethra on the glans was dripping with crystal clear semen. He was holding his head high and confidently, and I hoped that something would happen between us. However, moral reasoning pulled me back to reality, reminding me again and again that I must not do anything to let my husband down.

Entangled in such conflicting emotions, I didn't know what I said to Ming. I only knew that during that difficult time, I kept stealing glances at his crotch, hoping to see through his shorts and see his cock with bulging veins.

Finally, Ming said he was going home. A feeling of relief and loss emerged.

After saying goodbye to him, I let him go downstairs by himself.

After making sure he was gone, I lay on the sofa, thinking over and over again what had just happened, thinking about the briefs I had just seen in Ming's shorts, I reached out to unzip my shorts, put my hand into my shorts, and slowly stroked the clitoris soaked in the lewd water, and the small hole that was lubricated by the lewd water. Slowly, I rubbed the clitoris, feeling it engorged and erect, and slowly slid another finger into the small hole full of lewd water, slowly in and out, from shallow to deep, I unconsciously moaned in a low voice, and my hips were regularly thrust upwards, hoping that the small hole was thick enough to fill the lewd hole... Just as I was intoxicated in the unconscious lust of masturbation, I heard footsteps coming from the stairs from the first floor to the second floor. I hurriedly pulled out my fingers soaked in the lewd hole, and randomly tidied my clothes and pants to see who was on the stairs.

It’s me, Ming shouted.

What happened again came back, I responded to his reply.

After Ming went up to the second floor, he sat down with a few boys' briefs in his hand.

Ming said: I just realized I forgot to bring some panties for you to choose from when I got home. Since your husband is not here, you can help him choose. These ones are all made of good materials.

Ming may have noticed that my hands were wet with the vaginal fluid that had flowed down the inside of my thighs when I had just masturbated. He stared at the zipper on my hot pants that I had forgotten to zip up. He seemed to have discovered that I had just experienced an erotic scene of masturbation. He seemed to see through the desire in my heart, the desire to be wildly penetrated by a bulging, veiny cock. I didn't want to wait, I didn't want to wait for moral reason to pull me back to reality.

My instinctive reaction was to zip up my hot pants, and Ming also came to his senses.

I said: "Okay! I'll help my husband pick it out, but I don't know if this size is the same as the size of the briefs I usually buy for him."

He is about the same size as you, right?

To be clear: You can’t just pick them randomly! Briefs are different from boxers! If they don’t fit you well, it will affect your comfort. You have to think carefully.

I said: What should I do? Should I wait until my husband comes back and choose?

Ming said: Since you said your husband's size is the same as mine, I have a way to make you sure.

What method? I replied.

At this time, Dong quickly took off his sports shorts, leaving only a pair of tight briefs with a protruding crotch.

I was stunned. I had just been struggling to be penetrated by his throbbing cock in his briefs, but now? The throbbing cock was so close to me that only the briefs on my lower body were left.

My heart beat faster, my breathing quickened, and for a moment I could not feel Ming was also looking at my wildly heaving breasts. As he watched, Ming's huge cock became more intense, and I saw his cock with veins bulging inside his briefs trembling and shaking, as if it was about to burst his briefs that couldn't be any smaller! And I saw my pussy dripping with juice, and it was itchy, and I really wanted to be fucked by Dong's cock.

Finally, the stalemate was broken. Ming hugged me roughly, and I was shocked by his sudden action. I didn't know when Ming took off my spaghetti strap sleeveless cute top, and my CK lace chiffon underwear also fell to the side. When I came to my senses, Ming was licking my nipples with his clever tongue, which made my nipples itchy and soon stood up.

Ming's hands also slid restlessly from my chest to the buttons of my hot pants. In a short while, Ming was able to quickly take off the tight hot pants that were usually very difficult to take off. At this moment, I was left with only the CK lace thong that was too small to be any smaller. I became even more shy. Ming gently picked me up and walked to the bedroom. When I was lying on the Simmons spring bed with my husband, Ming was taking off his sports vest and the only thing left on his body was his briefs that were too small to be any smaller. I was very shy to see his erect penis, with blue veins, purple and fiery red glans, and some crystal clear vaginal fluid dripping from the urethra. His thick chest muscles and sparse chest hair made my heart beat faster and my breathing more rapid.

Ming slowly moved to the bedside, stretched out his hand and gently moved it over my body, gently and slowly, it was really comfortable. When his hand slowly slid towards my vagina, I slowly closed my eyes, relying entirely on my sense of touch to enjoy this tempting caress. Ming's teasing was so appropriate, he seemed to know the sensitive part of a woman's tactile nerves. After closing my eyes, I felt that the sensitivity of Ming's caress to me was magnified dozens of times, it was really comfortable.

I felt my pussy was flooded, the love juice kept flowing out, and it was extremely itchy inside.

I am looking forward to Ming's penis entering my body soon, but Ming knows women well and he knows when to make them feel extremely happy, so Ming is not in a hurry to attack.

Ming's hand moved to my pussy and he slowly rubbed it through my thong. I felt my pussy getting wetter and more itchy.

Ming then took off my thong, revealing my entire vagina and the appropriately thick and sparse pubic hair. Ming reached out to fiddle with my clitoris, slowly and gently, sometimes pinching it lightly, and my clitoris became engorged and erect again due to Ming's stimulation.

Ming lowered his head and kissed my clitoris, slowly teased my clitoris with his flexible tongue, and slowly bit my clitoris with his lips. All of this was a feeling I had never experienced before, it was so comfortable.

At this point, I couldn't help but moan. Because I live with my mother-in-law, and my father-in-law rarely moans when I have sex, so I have always been silent when having sex with my father-in-law. Today, the unexpected illicit love with Ming has greatly opened up my view of sex.

When Ming heard my faint and low moans, he teased me even harder. He pulled my hand to stroke his cock, the cock with bulging veins and a fiery red glans. He asked me to stroke it slowly. I seldom stroke my husband's cock, so my technique was a little awkward. Ming could sense my awkwardness, and he slowly taught me how to make his cock enjoy the pleasure of stroking it. Ming kissed my pussy while his hands kept caressing and wandering on my body. He also slowly moved his lower body cock to my mouth, suggesting that I use my mouth and tongue to serve Ming's cock. I have been making love with my husband for so long, but I have only given him oral sex a few times, so my oral sex skills are really not very good. I doubt whether I can satisfy Ming if he wants me to give him oral sex!

I tried to gently hold his cock in my mouth and stroke it slowly, but Ming Ming kept thrusting forward. His cock was bigger than a male's, how could I possibly swallow it all! I tried to open my mouth as wide as possible to accommodate Ming Ming's cock in and out, but it was really big, and I could only hold half of it in my mouth.

Gradually, I also heard Ming's moans. This was the first time I heard a man moan while having sex.

It seemed that I was encouraged. I sucked and stroked Ming's cock more seriously, sometimes licking the urethra on the cock with the tip of my tongue, and sometimes slowly licking the balls along the cock. Ming motioned for me to gently suck his balls. Ming's screams became louder and louder, and he kept shouting "I feel so good...baby...oh...it feels so good"

Ming also kissed my clitoris more vigorously. On the one hand, he slowly slid his fingers into the small hole soaked with vaginal fluid, slowly moving them in and out, and slowly scratching the flesh wall of the small hole, making me feel more itchy and more comfortable.

Ming was a little dissatisfied with my soft moans. He wanted me to abandon my morals and reserve and shout out. Gradually, I also screamed louder and louder, shouting "Oh... Ming... It feels so good... Really... So good... Oh... Oh... Oh..."

Ming's fingers slowly retreated to the entrance of the vagina, and after entering a little, he slowly massaged the small flesh pad above the vagina. From the vagina came a more numb and indescribable feeling, which became stronger and stronger. I have never experienced this feeling before, but it was really good. "Ming... It's so numb... So good... Quick... Quick... Fuck me a little... I can't stand it..."

I just felt my lewd water flowing more, and the feeling from my pussy became stronger. Finally, I also raised my hips to cater to Ming's attack on my pussy. The feeling became stronger and stronger, and my screams became more and more lewd unconsciously, "Ming...faster...it's so itchy...so good...so good...oh...Ming...deeper..."

I felt like I had to pee, so I told Ming to stop and said I had to pee.

Say it clearly: That is squirting, not peeing. Don't suppress it. Just relax, let it go and enjoy it.

The strong feeling finally broke through my reserve, and I opened my throat and screamed, "Ming... It feels so good... Oh... Oh

…Tomorrow…soon…soon…soon…it’s almost there…so good…I’m going to ascend to heaven…oh…”

A stream of liquid spurted out of the vagina and sprayed all over Ming's face.

I collapsed, my whole body twitching. It was the first time I felt such intense pleasure.

Ming pulled out his finger, and felt an inexplicable emptiness in the vagina. Ming slowly slid his finger, which was covered with love juice, towards the anus, and slowly massaged the outside of the anus.

Ming slowly slid his finger, which was covered with lewd water, into my anus and pushed forward slowly. I told Ming: Ming, it hurts! It's uncomfortable.

Ming said: Baby, please bear with it for a while, it will feel very comfortable soon. You are my baby, how can I bear to hurt you.

Slowly, I felt a wave of pleasure rising. Ming's tongue began to go in and out of my vagina, and began to fiddle with my vagina. Slowly, I began to moan again. I grabbed Ming's penis and continued to stroke it, slowly increasing the speed. I felt Ming's expression begin to be wanton. Ming finally couldn't help it, stopped his hand and straightened me, spread my legs, and he held his penis and slowly rubbed it on the entrance of my vagina, slowly rubbing it on my labia, but Ming just didn't enter.

I couldn’t stand it and kept shouting, “Ming…it’s so itchy…please put it in…I want a dick…”

Ming was massaging my clitoris while rubbing his penis against my vagina. Ming's glans was also covered with my vaginal fluid.

Finally, Ming straightened his cock, aimed his glans at my pussy, and slowly thrust forward. I felt my pussy slowly being stretched open by Ming's cock, and Ming's cock went in little by little, and then slowly pulled out. In this way, in and out, finally swallowing Ming's cock, my pussy felt extremely full and swollen.

At this time, Ming slowly pushed his hips forward to attack my vagina. Every time he went in and out, my vagina felt so full, but when Ming pulled out, my vagina felt empty again.

Ming increased the speed, and I could hear the regular sound of my buttocks slapping against Ming's and the "slurp...slurp" sound of the love fluid in my vagina.

Ming and I were moaning louder and louder. “Oh…baby…are you comfortable…do you want it deeper…do you want it bigger…”, “Oh…Ming…fuck me…deeper…faster…faster…oh…oh…give it to me…deeper…it feels so good…”

I don't know how long it took, but a large area of ​​the mattress was wet. Ming was still pushing forward vigorously.

Ming stopped and asked me to turn over and lie down.

He held his cock, aimed it at my pussy from behind, and entered it little by little.

Ming and I made love like dogs. He thrust in and out from behind. Ming's penis kept pumping in and out of my vagina. I didn't know how many times I had orgasmed. Every time I had an orgasm, my mind went blank and I screamed wildly without knowing what to say.

Ming penetrated me from behind, making me feel Ming's cock going deeper. My pussy also felt a strong sensation, and my moans became more and more hoarse and quieter, but the rhythm of my hips' thrusts matched better and better with Ming's. The sound of flesh hitting each other became louder and louder, and the sound of water replacing my moans. The sounds reached Ming's and mine, catalyzing the motivation for our sexual intercourse.

“Here it comes…almost…baby…faster…it feels so good…my dick feels so good when you squeeze it…”, “Ming…faster…it’s almost there again…so deep…so good…faster…oh…” I screamed with my last bit of strength.

Ming's movements were getting faster and faster, and I was about to reach another climax. "Ming...faster...I'm about to reach heaven again...Ming...you're so beautiful...oh...faster...deeper...faster..." Ming heard my moans and thrust forward even faster, reaching the deepest part of my vagina with each thrust. "Baby...so good...I'm about to reach heaven too...let's do it together...oh...so good..." "Pah pah...pah pah..." "Pu pu pu pu pu pu..."

Ming used up all his strength and finally shot his thick and hot semen into my vagina, burning my heart. Ming and I reached orgasm together, which was the strongest I had ever felt. I died again and talked nonsense again.

I don’t know how long it took, Ming got up, grabbed some toilet paper and wiped the semen that was slowly flowing out of the vagina.

Ming put on his clothes, kissed me lightly on the forehead and said to me: Baby, you are so great, even better than Xiaozhen.

I pinched his arm and said: Ming, you are going to die, why are you comparing me with Xiaozhen!

I said to Ming: "Go back quickly! Don't let Xiaozhen suspect you. Forget about what happened today! We are still friends, right?"

Ming said: "Baby, of course! I'm leaving now."

After Ming left, I got up and tidied the bed, but I felt a dull pain in my vagina. It turned out that the intense sex just now made my vagina red and swollen. I don't know how to explain it to my husband when he comes back tomorrow?

After this incident, I instinctively felt sorry for my husband and Xiaozhen, and thought I couldn't go on.

However, things don’t go as planned, and Ming’s affair continues to develop...
